<br />Metabolic changes in water content, total carbohydrates, total sugars, reducing sugars, anthocyanin, total free amino acids, proline and total indoles in shoots of "Anna" apple (Malus sylvestris, Mill) trees were investigated during dormancy and bud break under the effect of foliar application of four onion extract rates (5, 10, 15 and 20%). Flowering percentage and fruit yield characteristics (i.e., fruit-set, number of fruits tree-1 and fruit yield tree-1) were increased, while number of days recorded to reach full bloom were reduced with the application of both onion extract rates (15 or 20%). In addition, contents of total carbohydrates, total sugars, reducing sugars, anthocyanin, total free amino acids, proline and total indoles in shoots were significantly increased in floral buds, particularly during bud break. In contrast, the content of free phenols was reduced. The best results were obtained from the rate of onion extract at the level of 20% followed by 15% that could be recommended for early and high percentage of flowering and increased yield by regulating the metabolism of amino acids, including proline and indoles in apple floral buds.

<br />Schinus molle leaves, compost (SLC) incorporated with soil at different volume rates contrasted with control (soil alone), intending to improve and stimulating strawberry growth. Anecdotal accounts of SLC for these purposes the experiment has examined the impacts of SLC on strawberry growth and production responses. This research assessed the impacts of a six volume% (v: v) rates of SLC combined with soil at 0, 20, 40, 60, 80 and 100 of growing medium (field soil). The pots RCBD experiment included four replicates designed at the faculty of agriculture, Sana’a University. Plants cultivated in 20% SLC was significantly (p&lt;0.05) greater than control (field soil) in leaf area, yield, fruit weight and crown DM% by about 12.8% 25.8%, 20.4% and 101.6% subsequently. Meanwhile, transplants grown in 80 and 100% SLC developed the highest quantity of crowns and longer of peduncle. Transplants grown in 60% SLC was the poorest of flower number per plant measured with other treatments. Plants in 100% SLC showed the significantly downer of a DM% in the roots and crown parts 65.3% and 82.7% lower than control, respectively, nevertheless, composed the significantly greater 50.4% of fruit TSS than the control treatment. The variation between the SLC rates on the root characters showed that the 100% SLC increased the roots network volume cm3, root length cm2 root surface area cm2, specific root length cm. This study illustrates the benefit of that application SLC.

<br />The current study was planned to identify drought tolerant bread wheat genotypes based on physiological and yield traits. In this context, a set of 12 genotypes (Sarsabz, NIA-Sundar, NIA-Amber, Sassui, Khirman, Marvi-2000, NIA-Sarang, Kiran-95, NIA-Sunheri, Bhittai, Bathoor-08 and Tatara) were evaluated under normal and water stress conditions. Mean squares from analysis of variance exhibited that genotypes, treatments and genotype x treatment interaction showed significant differences (P&lt;0.05) for majority of the studied traits, indicating that there is significant variations are existed for physio-yield traits; therefore these genotypes may be preferred for further breeding programs in respect to drought stress. Regarding reduction percentage of genotypes under drought stress against normal water conditions, the minimum reduction was observed in Bathoor-08 for spike length and flag leaf area, Kiran-95 for grain yield plant, NIA-Sundar for seed index, Marvi-2000 for relative water content, Sarsabz for grains spike, whereas maximum but desirable reduction of stomatal dimension and density was displayed by Sarsabz and Tatara under water stress conditions, respectively. On the basis of drought tolerant indices, the genotypes Kiran-95, NIA-Sundar and Sarsabz showed lower values for tolerance index (TOL), trait stability index (TSI) and stress susceptibility (SSI), nevertheless it is believed that lower values of these indices show the less reduction in yield and its related traits due to water stress conditions hence can be tagged as tolerant genotypes for drought. Correlation results revealed that MP, SSI, TOL and TSI indices were correlated with grain yield under two conditions and they can be the appropriate indices for screening wheat genotypes.

<br />A field experiment was conducted to determine the effect of split application of nitrogen fertilizer on soil properties and maize yield. Two sites at Apatapiti layout, South gate of the Federal University of Technology Akure were used as the experimental sites. The experiment was designed in a randomized-complete-block design arrangement with three replications. The treatments consisted of urea applied at four levels of split application (0kgha-1, 60kgha-1 basal application, 30kgha-1 basal application+ 30kgha-1 applied at 15 days after planting, 30kgha-1basal application + 20kgha-1applied at 15 days after planting + 10kgha-1applied at 30 days after planting). The plot size was 2 m x 2 m with 1 m space between plots and blocks. Maize (Zea mays L. var. TZB-SR) was planted at 75 cm by 25 cm spacing and 10 were sampled per unit for yield parameters. Split application of urea (30kgha-1basal application + 20kgha-1applied at 15 days after planting + 10kgha-1applied at 30 days after planting) significantly (p&gt;0.05) increased N content of the soil. There was no significant (p&gt;0.05) difference with regard to other nutrients. Soil pH was significantly (p&gt;0.05) reduced as a result of urea application in all treatments. Split urea fertilizer application retained a considerable amount of nitrogen in soil even after the harvest of maize. Exchangeable cations were not significantly different from one another as well as CEC. Split application of urea (30kgha-1basal application + 20kgha-1applied at 15 days after planting + 10kgha-1applied at 30 days after planting) gave the highest grain yield of maize for both sites. Also, plant biomass of both split application were better than the basal application and control.

<br />Maize (Zea mays L.) forage quality traits are reported to show varying responses to abiotic stress. Four trials were conducted in Sudan (Africa) during the summer and winter seasons (2013 &ndash; 2014) at two locations: Shambat (normal soils) and Soba (salt affected soils) to investigate the effects of abiotic stress on the nutritive value of maize forage. In each trial nine maize genotypes were studied under two watering regimes arranged in split plot experiment in randomized complete block design. The compound effect of salt, water and heat stresses created by the combination of locations, seasons and watering regimes were used to investigate the effect of abiotic stress on forage quality at silk initiation and dough growth stages. Character associations under stressed and none stressed conditions were studied. NDF, ADF, CP, forage yield and related traits were measured. Abiotic stress significantly lowered the nutritive value in terms of crude protein, digestibility and intake potential. Digestibility under stressed condition was slightly improved as growth stage advanced from silk initiation to dough stage. Correlations under non stress conditions between forage yield and quality traits were either favorable with NDF and weak or insignificant with ADF and CP. Under stress conditions, similar trend generally exists apart from the unfavorable correlation of CP with each of yield and ADF, in addition to earliness with NDF. The compound effect of salt, water and heat stresses have adverse impact on the nutritive value of maize forage. Varieties combining high performance in quality and forage yield could be developed under non-stressed or stressed conditions.

<br />Compared to sole cropping, intercropping systems can more efficiently use the existing resources which ultimately lead to improved plant growth and dry matter accumulation. So, most of the farmers in developing countries can follow the intercropping systems with high yielding crop combinations. The experiment was carried out at the Crop Farm of Eastern University, Sri Lanka in 2018 to investigate the growth and dry matter accumulation in okra (Abelmoschus esculentus L.) as influenced by different planting patterns under okra-cowpea (Vigna unguiculata L. Walp) intercropping in sandy regosol. The experiment was laid out in a Randomized Complete Block Design (RCBD). Treatments were okra as a sole crop (T1), cowpea as a sole crop (T2), alternative planting of okra and cowpea (T3), 60/150 cm paired row planting of okra with two rows and three rows of cowpea in between paired rows (T4 and T5) and 75/120 cm paired row planting of okra with two rows and three rows of cowpea in between paired rows (T6 and T7). Plant height, root length, fresh and dry weights of plant, leaf area, leaf area index, canopy width and cumulative yield of okra were higher in T5, while chlorophyll content showed no significant difference (P&gt;0.05) with different planting patterns. The present study concluded that 60/150 cm paired row planting of okra with three rows of cowpea in between paired rows (T5) would be the most suitable planting system in sandy regosol to achieve better growth and dry matter in okra.

<br />Due to growing population, there is an increasing demand of rice production but the productivity of rice is lessened day by day. To overcome this problem various biotechnological tools can be used for developing various rice varieties. However, the lack of a simple and efficient protocol for callus induction, embryogenic callus formation and quick plant regeneration in this cereal crop. In this study embryogenic calli from mature seeds of five indica rice varieties viz. Binadhan-5, Binadhan-6, BRRI dhan-48, BRRI dhan-58 and IR-64 were observed that is done in four different types of media composition. The highest callus induction were observed in media containing Sucrose as a carbon source. Among those varieties Binadhan-6 and BRRI dhan-48 showed highest rate of callus induction respectively. This study will be useful for selecting suitable callus induction medium for callus induction in future that will be useful for not only national but also international plant breeders for producing new variety and so on.
